1 Claim.

to the rear of a oor polisher so that it may ben readily attachedthereto when it is desired to apply wax to the oor. The container isdivided into two chambers by a horizontal partition. The upper chamberis adapted to contain liquid wax and the partition is provided with aValved opening leading to a bottom distributing chamber. The bottom ofthe lower distributing chamber is closed by a ne mesh screen whichserves to support a porous wax spreading cloth and to distribute the waxover the cloth. An operator for the valve extends upwardly through theupper chamber and is positioned to be contacted by the propelling handleof the polisher so that downward movement of the handle will open thevalve when it is desired to apply wax to the floor.

Other objects and advantages of this invention will become apparent asthe description proceeds when taken in connection with the accompanyingdrawings in which:

Figure 1 is a side elevation of a floor polisher with the waxingattachment of this invention applied thereto;

Figure 2 is a cross-sectional view of the waxer attachment taken on line2-2 of Fig. 1, looking in the direction of the arrows; and

Figure 3 is a plan view of the polisher and attachment of Fig. 1.

Referring to the drawings the reference numeral I represents the mainframe as a floor polisher of known construction having a plurality ofrotatable brushes I I driven by a motor housed within the hood I2. Thepolisher is adapted to be propelled about during polishing operation byhandle I3 pivoted to the frame I0 by pivot pintles I4.

A wax container I5 is attached to the pintles I4 by a pair of arms I6,having slots I1 which slide over the pintles I4 inside the bail arms ofthe handle I3 and pivoted to the container I5 by pintles I8 preferablywelded to the side walls of the container I3 as shown in Fig. 2. Thecontainer I5 is formed with a top portion I9 and a bottom portion 20which extends about the periphery of the top portion I9 and has a ledge2| extending inwardly toward the center of the container I5. The ledge2I forms a support for a wax distributing screen 22 which supports aporous cloth wax applicator 23 clamped about the periphery of bottomportion 20 by a clamping band 24 held in clamping position by areleasable latch 25.

The interior of the top portion I3 of the container I5 is divided intotwo chambers by a horizontal partition 26 having a flange 21 preferablybrazed or otherwise secured to the inner wall of the portion I9. Thepartition 26 is provided with a central opening 28 in which a valve seatmember 29 is suitably secured. The valve seat 29 cooperates with a valve30 preferably made of rubber such as neoprene which is not affected byoils in the liquid wax. A Valve stem 3| has its lower end secured to thevalve 30 and extends upwardly through a guide 32 secured in the top ofthe container I5 by a closure 33 which may be brazed or otherwisesecured to the container I5.

The valve 36 is spring-biased upwardly by a spring 34 resting againstthe partition 26 at its lower end and at its upper end against adownwardly facing disc 35 which abuts a shoulder 36 on the valve stem3I. A pin 31 passes through the upper end of the stem 3l to form a stopto prevent excess opening of the valve 30.

The upper end of the stem 3I is positioned immediately below a roller 38clamped to the handle I3 by a suitable clamping band 39. The containerI5 is provided with a filling opening closed by a cap 40 as shown inFig. 2.

Operation When it is desired to apply wax to the surface being polishedthe closure 40 is removed and the container I5 filled with wax as shownin Fig. 2. The closure 40 is then replaced and the slots I1 in the armsI6 slid over the pintles I4 on the inside of the handle bails of thehandle I3. Since the arms I6 are pivoted to the pintles I4 and to thepintles I8 the wax applying cloth 23 will rest horizontally upon thesurface being polished immediately to the rear of the polisher.

The polisher is then propelled about over the surface being polished andwhen it is desired to apply wax the handle I3 is depressed so that theroller 38 will contact the top of the Valve stem 3I and open the valve30 to supply liquid wax to the top of the distributing screen 22 and tothe wax applying cloth 23.

From the foregoing, it can be seen that according to this invention asimple attachment is provided for a floor polisher for the applicationof liquid wax to the surface being polished which requires nomodification of the polisher, except the application of the clampingband 33 to the handle I3.

While I have shown but a single embodiment of my invention it is to beunderstood that that embodiment is to be taken as illustrative only andnot in a limiting sense. I do not wish to be limited to the particularstructure shown and described but to include all equivalent variationsthereof except as limited by the scope of the claim.

A combined floor polisher and waxer comprising, a body, polishingbrushes rotatably carried by said body, a propelling handle pivoted tosaid body and extending upwardly and rearwardly therefrom duringpolishing operations, a wax containing receptacle at the rear `of saidbody, a wax applicator secured to the bottom of said receptacle, a pairof arms pivoted to said receptacle and to said bodywhe'by'sa'id'receptacle is propelled along behind said body with saidapplicator resting upon Vthe surface being polished, valve means in saidreceptacle for dis- 4 pensing wax to said applicator and an actuator forsaidvalve means positioned to be contacted by said handle upon downwardpivotal movement thereof.
